Embodiment Construction

[0053] Hereinafter, a detailed description of various embodiments of the present invention will be disclosed with reference to the accompanying drawings. All examples herein should be considered part of the general description, and thus may be combined in any way in general. Individual features and methods of the various embodiments may be combined or exchanged unless such combination or exchange is clearly contradictory to the overall function of the seven-speed dual clutch transmission device.

[0054] Briefly described, the present invention relates to a compact dual clutch seven-speed transmission arrangement for use in a hybrid vehicle. The transmission arrangement includes a dual clutch gearbox and an electric machine coupled to a 4th gear of the transmission. The transmission arrangement thus allows propulsion from both the internal combustion engine and the electric machine. The transmission also allows propulsion from both engines to be sent to the driveline simulta...

Abstract

Dual-clutch seven speed transmission arrangement and method for use with a transverse engine arrangement in a hybrid vehicle wherein a dual-clutch gearbox comprises an input shaft for odd drive gears (12) and an input shaft for even drive gears (11), respectively arranged in connection to a first (12) and a second (11) clutch. The input shaft for even drive gears (11) is a hollow shaft enclosing said input shaft for odd drive gears (12) and the input shaft for odd drive gears (12) is arranged to host four odd drive gears. The input shaft for even drive gears (11) is arranged to host three even drive gears and a reverse drive gear, and in connection to said input shaft for even drive gears (11) an electric motor (15) is arranged.

Description

technical field [0001] The present invention generally relates to a compact dual clutch seven speed transmission arrangement for a hybrid vehicle. Background technique [0002] Hybrid vehicles, such as hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV), typically include gears of the gearbox for the drive train. This practice is commonly used in hybrid vehicles and conventional vehicles, such as those with a single internal combustion engine. [0003] Unlike a transmission device for a conventional vehicle, a transmission device for a hybrid vehicle needs to accommodate power input from various sources. Furthermore, hybrid vehicles are often made to be energy efficient, necessitating the use of energy efficient gearboxes. [0004] It is known in the art to use dual clutch transmissions for vehicles in order to reduce shift times and optimize fuel consumption relative to the use of conventional automatic or manual gearboxes. The dual clutch transmis...
